Woocommerce - Set Minimum quantity for products in cart

Restricting user to buy minimum quantity for products in woo-commerce is a pretty cool thing, we can achieve it by following the below steps

Step1:

1. Collect the product ids for which you wanted to restrict the quantity during checkout, store them in a array

<?php

$pd_min_quantity= array( 

array( 'id' => 3587, 'min' => 99),

array( 'id' => 2554, 'min' => 87),

array( 'id' => 5587, 'min' => 52),

array( 'id' => 4488, 'min' => 40),

       array( 'id' => 2555, 'min' => 80),

);

?>

Step2:

Add Following code to your themes - > functions.php

Note: don't forget to update your product ids and quantity 

<?php

add_action( 'woocommerce_check_cart_items', 'restrict_product_quantity' );

function restrict_product_quantity() {

if( is_cart() || is_checkout() ) {

global $woocommerce;

$pd_min_quantity= array(

array( 'id' => 3587, 'min' => 99),

array( 'id' => 2554, 'min' => 87),

array( 'id' => 5587, 'min' => 52),

array( 'id' => 4488, 'min' => 40),

       array( 'id' => 2555, 'min' => 80),

);

$i = 0;

$odd_prod = array();

foreach( $woocommerce->cart->cart_contents as $pd_cart ) {

foreach( $pd_min_quantity as $pd_quantity ) {

if( $pd_quantity['id'] == $pd_cart['product_id'] ) {

if( $pd_cart['quantity'] < $pd_quantity['min'] ) {

$odd_prod[$i]['id'] = $pd_cart['product_id'];

$odd_prod[$i]['in_cart'] = $pd_cart['quantity'];

$odd_prod[$i]['min_req'] = $pd_quantity['min'];

}

}

}

$i++;

}

if( is_array( $odd_prod) && count( $odd_prod ) > 1 ) {

$message = '<strong>Minimum quantity per product should be added.</strong><br />';

foreach( $odd_prod as $odd_prods ) {

$message .= get_the_title( $odd_prods['id'] ) .' requires a minimum quantity of '

. $odd_prods['min_req'] 

.'. You currently have: '. $odd_prods['in_cart'] .'.<br />';

  $cart_contents = array();
  $cart = WC()->session->get( 'cart', null );
   if ( is_null( $cart ) && ( $saved_cart = get_user_meta( get_current_user_id(), '_woocommerce_persistent_cart', true ) ) ) {
    $cart = $saved_cart['cart'];
  } elseif ( is_null( $cart ) ) {
    $cart = array();
  }

  if ( is_array( $cart ) ) {
    foreach ( $cart as $key => $values ) {
      $_product = wc_get_product( $values['variation_id'] ? $values['variation_id'] : $values['product_id'] );

      if ( ! empty( $_product ) && $_product->exists() && $values['quantity'] > 0 ) {
        if ( $_product->is_purchasable() ) {
         $session_data = array_merge( $values, array( 'data' => $_product ) );
          $cart_contents[ $key ] = apply_filters( 'woocommerce_get_cart_item_from_session', $session_data, $values, $key );
        }
      }
    }
  }
  return $cart_contents;
}

// Step2:

add_action('wp_loaded', function() {
    if(!is_object(WC()->session)) {
    return;
  }

  global $allowed_cart_items;
  // I am adding products with ID 5395,5138,5046,5137,5134,5133,5131 as a combination.
  global $restricted_cart_items;
  $restricted_cart_items = array(5395,5138,5046,5137,5134,5133,5131);

  foreach(aelia_get_cart_contents() as $item) {
    if(in_array($item['data']->id, $restricted_cart_items)) {
      $allowed_cart_items[] = $item['data']->id;
    }
  }

  // Step3:

  add_filter('woocommerce_is_purchasable', function($is_purchasable, $product) {
    global $restricted_cart_items;
    global $allowed_cart_items;

    if(!empty($allowed_cart_items)) {
           $is_purchasable = in_array($product->id, $allowed_cart_items) || in_array($product->id, $restricted_cart_items);

Woocommerce - Display Notifications

Display notification in Woocommerce when a user checkouts a product.

Here is the code

1. We need get the order count 

<?php

global $woocommerce;

$order_count = wc_get_customer_order_count( $current_user->ID );
if($order_count>=1) { ?>
<div class="quantity"><?php echo $order_count; ?></div>
<?php } ?>

2. Alright!!
We got our order count, but we should allow user to show his notifications only when logged in. So we have to restrict user.

<?php if ( is_user_logged_in() ) { // If user logged in  ?>
<a href="URL">Show Notifications</a> // "URL" Add your Notifications Page URL
<?php }
 else { // If user not logged in , We will Navigate him to My account page ?>
 <a href="<?php echo get_permalink( get_option('woocommerce_myaccount_page_id') ); ?>">Show Notifications</a>
 <?php } ?>

3. Finally!! 

We have to display all the order details in the notifications page.

<ul class="notifications">
<?php
$customer_orders = get_posts( array(
    'numberposts' => -1, // No of notifications to display
    'meta_key'    => '_customer_user', // Meta Key to get customer details
    'meta_value'  => get_current_user_id(),
    'post_type'   => wc_get_order_types(),
    'post_status' => array_keys( wc_get_order_statuses() ),
) );

foreach($customer_orders as $customer_order)
{
echo "<li>"; ?>

<a href="<?php bloginfo('url'); ?>/my-account/view-order/<?php echo $customer_order->ID; ?>"> <?php echo $customer_order->post_title; ?> </a>
<?php
if($customer_order->post_status == "wc-cancelled"){$orderclass = "alert-danger";}else {$orderclass = "alert-info";} // We can add some styles by adding a dynamic class based on the order status, "$orderclass" is the class varaiable ?>
<span class="<?php echo $orderclass; ?>"> <?php  echo  $customer_order->post_status; ?> </span>

<?php echo "</li>"; } ?>

</ul>

4. Done!!
